5.1.2.3 Child Node

The node has the following child nodes, which are all optional. All of the nodes except comment are basically used for a transfer function file.

comment

A description of the file. Any string is acceptable.

SynchronousAverage

A number of a repetition of signal for transfer function measurement (TSP signal). An natural number is required.

TSPpath

A path to an audio file for transfer function measurement (TSP signal). A string is required.

TSPOffset

An offset for transfer function calculation. A natural number is required.

PeakSearch

This node have attributes: from and to. This information is used for specifying the range of the peak detection of the direct sound for transfer function calculation. These attributes are mandatory, and must be natural numbers.

nfft

The length of Fourier transform for transfer function calculation. A natural number is required.

samplingRate

The sampling rate of the recorded signals for transfer function measurement. A natural number is required, and usually we use 16000, i.e., 16kHz sampling.

signalMax

The maximum amplitude of the recorded signal for transfer function measurement. A natural number is required. If the wave file’s sample width is 16bit, the value must be 32767.

TSPLength

The length of a signal for transfer function measurement (TSP signal) in sample. A natural number is required. Usually, we use 16384 samples.
